Skin performance issues: High CPU usage from RunCommand plugin

[Sacha00Z]

Is there a way of optimising my configuration?

I'm using the RunCommand plugin to call a PowerShell command "Get-Service". I have a series of measures that check the running state of a series of Windows Services. My PowerShell command returns the state of the service (Running/Stopped)

The problem is that my skin absolutely hammers my CPU, occupying 100% CPU every refresh cycle, and 45% of my battery usage (PowerShell) when unplugged. Additionally, meters are not updating on the first refresh cycle. I could increase the update interval if it weren't for the fact that meter updates only occur after the second update cycle.

Setup
(Details ommitted)

Code: Select all

[Rainmeter]
Update=25000
OnUpdateAction=[!CommandMeasure measureSvc1 "Run"][!CommandMeasure measureSvc2 "Run"][!CommandMeasure measureSvc3 "Run"][!CommandMeasure measureSvc4 "Run"][!CommandMeasure measureSvc5 "Run"]

[Variables]
; Configure your solution here. Label to display in skin and the name of each Windows Service to query
Line1Label=Some Service
Line1SvcName=_SomeService1
Line2Label=Another Windows Service
Line2SvcName=_AWinSvc2
Line3Label=SQL Server
Line3SvcName=MSSQL$SQLEXPRESS
Line4Label=Something else
Line4SvcName=com.dockeing.service
Line5Label=Last thing

Measures

Code: Select all

[measureSvc1]
Measure=Plugin
Plugin=RunCommand

; (...copy paste measure 5 times...)

Meters

Code: Select all

; Line 1

The CPU spike is happening because you are running five RunCommand commands at the same time. There is no risk by itself running five commands simultaneously, but the spike is happening due to your commands being resource intensive.

I am not sure if you really need to run them simultaneously. If you can run them one after another, then you can do it this way:

Code: Select all

[Rainmeter]
OnUpdateAction=[!CommandMeasure measureSvc1 "Run"]

[measureSvc1]
Measure=Plugin
Plugin=RunCommand
FinishAction=[!CommandMeasure measureSvc2 "Run"]

[measureSvc2]
Measure=Plugin
Plugin=RunCommand
FinishAction=[!CommandMeasure measureSvc3 "Run"]

[measureSvc3]
Measure=Plugin
Plugin=RunCommand
FinishAction=[!CommandMeasure measureSvc4 "Run"]

[measureSvc4]
Measure=Plugin
Plugin=RunCommand
FinishAction=[!CommandMeasure measureSvc5 "Run"]

[measureSvc5]
Measure=Plugin
Plugin=RunCommand

Additionally, meters are not updating on the first refresh cycle. I could increase the update interval if it weren't for the fact that meter updates only occur after the second update cycle.

I think this is due to missing bangs.

For example, here and similarly everywhere:

Code: Select all

IfMatchAction2=[!SetOption MeterIconLine1 ImageName #@#Images\Running.png][!SetOption MeterValueLine1 Text ""][!UpdateMeter MeterIconLine1][!Redraw]

you set some option to two meters, but you update only one of them.

This sequence should now work:

Code: Select all

[!SetOption MeterIconLine1 ...][!SetOption MeterValueLine1 ...][!UpdateMeter MeterIconLine1][!UpdateMeter MeterValueLine1][!Redraw]
